Be it known thatfL'JAooB H. MILLER, a citizen of the United States,: residing at (Wesson, in the county of Cambria and State of Pennsylvania, have invented certain'new and useful Improvements in Grease-Cups, of which i the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in grease cups,'and"it has for an object to provide a device of this general character having novel and improved means whereby i the lid is effectively maintained against separation from the'cup proper and wherein the lid is constructed in a manner to'facilitate the desired application of the greasepanying drawings, wherein;

Figure 1 is vertical sectional view taken through a grease cup constructed in accordance with an embodiment of my invention.

Fig. 2 is also a vertical sectional view taken.

7 through my improved grease cup, the line of section being at substantially right angles to the line of section in Fig.1.

Fig. 3 is a viewin top plan of the device as disclosed in Figs. 1 and 2.

Fig. 4 is a horizontal sectional View taken through the central portion of my improved device, and

- Fig. 5 is a fragmentary view in top plan of the retaining ring as herein embodied.

' As disclosed in the accompanying drawings, C denotes a grease cup having its inner wall threaded, as at 1, from end to end. The cup C is preferably ofatype particularly adapted for use in connection with the side rods of a locomotive tolubricate a crank pin coacting therewith,a1though I do not wishv Specification-of lt.e tcei:sPatent; fP ate nted gina'l portion -of the head 3 is defined an outstanding flange 4 which 'coacts withjthei adj acentend of the cup (l to limitthe extent Octal-1,1921:

particular'use' I o 1 r L denotesthe lid its entir'ety for the be understood' 'as' limiting myself to;

cup (I and said lid comprises an elongated tubular body 2 adapted to extend within thecup C. The inserted end of the bodyl l is: open while th e'oppositeior outer end is clOsedPby thev integral head 3. The mar of movement of the lid L, or more particu-- larly the body 2, inwardly. of; the cup C.

The head 3 is also providedfwith' anjoutstand ng lug 5 angular 'inplan to iiprovide means whereby a wrench or other tool may be effectively engaged with the lid top'roperly and conveniently manipulatethe lid.

The .inserted end'portion of the body 9. is provided With an outstanding continuous flange 6, the periphery-of. which is-relatively broad and has threaded engagement with the. internal threaded wall 1 of the cup C so that upon requisite rotation of the lid L, the body 2 may be moved inwardlyor outwardly of thecup as desired, I a I After the insertedend portion of the lid L has been applied withinthe cup C,a re,-

taining ring- 7 [is welded or otherwise sel curely affixed to the outer end or edge ofthe wall of the cup" C and said ring, when applied, has its inner marginal portion partially overlying the outer. end of thecup C to i flange 6 engages to limit. the outward moveworking'position. a i

The wall of the body 2 is' provi ded with a longitudinally extending and relatively wide slot 9 extending from the flange 6 to a immediately adjacent the head 3. I

When'the lid L is extended with-respect to the cup C, the'hard grease or kindredlubricant may be readily placed within the body 2 through the slot 9, and after which. the lid 'L is rotated in a direction to cause the lid L, or more particularly'the body: 2 thereof, to extend within the cup G. .By

provide a flange or stop 8 with which the: I Y .90' ment of the lid. The ring 7 preferablycomprises a pluralityofisections so that'the. same'may-loe properly arranged in applied or point l this arrangement, the grease or lubricant f can be .put in without the necessity'of entirely removing the lid L and this is of particular importance as it avoids the damaging ofthe threads 1 which often occurs in connection with lids which are entirely separable from the cup. Furthermore, my improved type of grease cup prevents loss of the lids as so often occurs with the types of grease cups now generally in use.

' From the foregoing description it is thought :t'o'be obvious that a grease cup constructed in accordance with my invention is particularly well adapted'ffor use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my. invention in practice lexceptas here inafter claimed.

of saidbody being provided with a slot extending longitudinally thereof, the outer end portion of thelid'being provided with a permanentflangecoacting with the cup to limit the movement of the lid inwardly. of thecup u. 1
